- Method Detail
  - getBufferSize
```
int getBufferSize()
```
    Returns:
    
    the buffer AKA page size in bytes of the associated OByteBufferPool.
  - getBuffersInThePool
```
int getBuffersInThePool()
```
    Returns:
    
    the number of the free buffers currently in the pool of the associated OByteBufferPool.
  - getPreAllocatedBufferCount
```
long getPreAllocatedBufferCount()
```
    Returns:
    
    the number of the allocated buffers of the associated OByteBufferPool, this does not include the overflow buffers.
  - getOverflowBufferCount
```
long getOverflowBufferCount()
```
    Returns:
    
    the number of the allocated overflow buffers of the associated OByteBufferPool.
  - getAllocatedMemory
```
long getAllocatedMemory()
```
    Returns:
    
    the current total memory allocation size in bytes of the the associated OByteBufferPool, including the overflow buffer allocations.
  - getAllocatedMemoryInMB
```
long getAllocatedMemoryInMB()
```
    Returns:
    
    the current total memory allocation size in megabytes of the the associated OByteBufferPool, including the overflow buffer allocations.
  - getAllocatedMemoryInGB
```
double getAllocatedMemoryInGB()
```
    Returns:
    
    the current total memory allocation size in gigabytes of the the associated OByteBufferPool, including the overflow buffer allocations.
  - getPreAllocationLimit
```
long getPreAllocationLimit()
```
    Returns:
    
    Maximum amount of bytes which may be allocated using big chunks of memory
  - getMaxPagesPerSingleArea
```
int getMaxPagesPerSingleArea()
```
    Returns:
    
    Amount of pages which fit in single big chunk of memory preallocated during page allocation request.
  - getPoolSize
```
int getPoolSize()
```
    Returns:
    
    Size of the pool which contains records which were allocated but now were fried to the pool by database.
